Most of the cars on those lots out there come from the auction. I had a buddy who bought a 05 CTS from one of them. A day after he bought it he had to replace the battery. Then another one the day after that. He finally took it to a dealer and they found a master disconnect switch, the same one we use on the race cars. Well the dealer spent 3 days trying to trace everything and could not fix it. He takes it back to where he goy it and they tell him to take a hike. So now he has this 14,000.00 car that he has to open the glove box and shut down everytime he gets out.
